why Old Testament? What about Romans 1?
 Because that, when they knew God, they have not glorified him as God, or given thanks; but became vain in their thoughts, and their foolish heart was darkened.  For professing themselves to be wise, they became fools.  And they changed the glory of the incorruptible God into the likeness of the image of a corruptible man, and of birds, and of fourfooted beasts, and of creeping things.  Wherefore God gave them up to the desires of their heart, unto uncleanness, to dishonour their own bodies among themselves.  Who changed the truth of God into a lie; and worshipped and served the creature rather than the Creator, who is blessed for ever. Amen.

And as they liked not to have God in their knowledge, God delivered them up to a reprobate sense, to do those things which are not convenient;  Being filled with all iniquity, malice, fornication, avarice, wickedness, full of envy, murder, contention, deceit, malignity, whisperers,  Detractors, hateful to God, contumelious, proud, haughty, inventors of evil things, disobedient to parents,
 Foolish, dissolute, without affection, without fidelity, without mercy.  Who, having known the justice of God, did not understand that they who do such things, are worthy of death; and not only they that do them, but they also that consent to them that do them.
